Quote of the Week

The downside of skepticism: it can easily turn into an arrogant position of a priori rejection of any new phenomenon or idea, a position that is as lacking in critical thinking as the one of the true believer, and that simply does not help either science or the public at large.

Massimo Pigliucci, Italian-American philosopher and biologist
